I admire Hamlet’s directness here. If I had suspicions about my friends’ motivations, I don’t think I’d confront them. I think I’d try and work it out round and about, try and get some time to explore what I knew. Hamlet does a little of this but he just comes out and asks them what the heck is going on. If he were Polonius, he’d send someone to follow them. If he were Gertrude, he’d cozy up to them. If he were Claudius, he’d have them killed (Oh wait! He does that later.) If he were Ophelia, he’d just accept his crappy fate. And if he were the Player, he’d act this thing out.
